Abstract
The utility model relates to an elastic rushing core tooth-profile chopping machine head used for chopping file cutter tooth-profile and the tooth-profile of words graving steel plate with low noise. The utility model is composed of a crankshaft 2, a crank connecting rod 3 and an elastic rushing core driven by the crank connecting rod for moving from top to bottom, and the elastic rushing core is composed of a connection shaft 6, a coupling nut 4, a spring 5, a rushing core 7, etc. The utility model eliminates the mainly noise source of the existing tooth-profile chopping machine head, and the utility model has the advantages of low noise, little pollution, etc. The utility model reduces the influence of the noise on the physical and mental health of workers.
Description
The utility model relates to a kind of low noise elasticity of cutting file groove and stencil steel board groove that is applicable to and cuts the tooth head towards the core tooth.
The existing tooth head of cutting generally all is to be rotated by the driven by motor camshaft, make cam rotate continuous impact lever one end, percussion is towards the core middle part about making the lever other end, compression is towards the spring on core top, drive moves up and down towards core, makes towards the marking knife impact workpiece of core bottom and finishes the technology that workpiece is cut groove; Its weak point is: all will produce bigger noise at the continuous impact lever of cam high speed rotating and when making the lever other end constantly impact towards core, the unit noise is up to more than the 99-105 decibel during according to test processing pincers worker topping line, the unit noise is up to more than 85 decibels during machining and shaping topping line, thereby the physical and mental health of not only having polluted environment but also having endangered labourer.
The purpose of this utility model designs exactly and a kind ofly can reduce noise, the protection environment, and the able-bodied elasticity of protection labourer is cut the tooth head towards core.
The purpose of this utility model realizes by following structure: elasticity towards core cut the tooth head include belt pulley, head of a bed body, towards core, panel, pressing plate, cutter holder and marking knife; It is characterized in that in head of a bed body top, having a bent axle by the belt pulley drive, slide on the bent axle and be with a crank connecting link, the connecting axle that is connected by connecting pin is arranged in the crank connecting link bottom, connect by the attaching nut between two connecting axles, be combined with a guideway in the connecting axle basal sliding, guideway is fixed in the pilot hole of core, and a spring is arranged between attaching nut and guideway; In order to make connecting pin wear-resisting, can on connecting pin, overlap a wear-resisting copper sheathing; For the frictional force between bent axle and the crank connecting link on it is reduced, can on bent axle, overlap a bearing in the crank connecting link; Guideway squeezes in the pilot hole of core by brute force, and reinforces its affixed with towards core with ending hook bolt.
Use of the present utility model is as follows: it is to drive the bent axle high speed rotating by power by belt pulley that elasticity is cut the work of tooth head towards core, the crank connecting link that is connected with bent axle, connecting axle are moved up and down with the core that dashes that links to each other with spring, guideway on the connecting axle, and the marking knife on core then can cut groove on workpiece.
The utility model compared with prior art has the advantage that noise is low, environmental pollution is little; Because of it has reduced by two main noise source, (noise source that cam and lever impact and the other end of lever and the noise source of impacting) towards core, make its empty wagons noise on average descend 18～21 decibels, the work noise 9-12 decibel that on average descends, thus also reduced able-bodied influence to labourer.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the S-S of Fig. 1 is to cutaway view;
Fig. 3 is that the H-H of Fig. 2 is to cutaway view.
Among the figure: 1, head of a bed body, 2, bent axle, 3, crank connecting link, 4, attaching nut, 5, spring, 6, connecting axle, 7, towards core, 8, cutter holder, 9, marking knife, 10, connecting axle, 11, bearing, 12, wear-resisting copper sheathing, 13, guideway, 14, panel, 15, pressing plate, 16, belt pulley, 17, pilot hole, 18, end hook bolt.
Below in conjunction with drawings and Examples the utility model is further described:
Elasticity includes head of a bed body 1 towards the core head as shown in Figure 1, belt pulley 16, and towards core 7, marking knife 9 and cutter holder 8 have a bent axle 2 by belt pulley drive rotation on the top of head of a bed body.Bent axle 2 middle parts are with bearing 11 and crank connecting link 3, the connecting axle 6 that is connected by connecting pin 10 is arranged in the crank connecting link bottom, outside connecting pin, be with a wear-resisting copper sheathing 12(as shown in Figure 2), one attaching nut 4 is arranged between two connecting axles, the connecting axle basal sliding is furnished with a guideway 13, guideway is squeezed in the pilot hole 17 of core 7, and by ending hook bolt 18 reinforcings, one spring 5 is arranged between attaching nut and guideway, head of a bed body 1 and panel 14, pressing plate 15 constitutes one makes the die cavity (as shown in Figure 3) that can move up and down towards core.Power rotates with 1400 rev/mins speed by belt pulley 16 drive bent axles 2 during use, turn in the process of peak by minimum point at bent axle 2, bent axle is by crank connecting link 3, nut 4, connecting axle 6, and be fixed on guideway 13 on the core 7 and drive and move upward towards core 7, turn in the process of minimum point by peak at bent axle 2, towards core is connecting rod 3, nut 4, and connecting axle 6 and spring 5 move downward under the precompression effect that the guideway on core 13 produces with solid.Behind marking knife 9 contact workpieces, relatively no longer move downward towards core, make spring that deformation take place once again, thereby make workpiece under the deformation energy effect of the kinetic energy of core and spring, obtain groove.As needing the groove of the different size of processing work, the attaching nut 4 that can outward winding selects for use different spring 5 to be enclosed within the connecting axle bottom, screws nut and by adjusting the precompression that nut comes regulating spring, then can process different grooves.
Claims (4)
1, a kind of elasticity is cut the tooth head towards core, and it includes belt pulley 16, head of a bed body 1, towards core 7, panel 14, pressing plate 15, cutter holder 8 and marking knife 9; It is characterized in that: a bent axle 2 by the belt pulley drive is arranged in head of a bed body top, slide on the bent axle and be with a crank connecting link 3, the connecting axle 6 that is connected by connecting pin 10 is arranged in the crank connecting link bottom, one attaching nut 4 is arranged on connecting axle, the connecting axle basal sliding is furnished with a guideway 13 and is connected in towards in-core, between nut and the guideway on the core spring 5 is arranged.
